FujiFilm X-E3 vs Panasonic GX850: The Ultimate 2017 Entry-Level Mirrorless Shootout

When exploring the lively mirrorless camera market of 2017, two contenders stand out as compact, affordable, and feature-packed options from seasoned manufacturers: FujiFilm’s X-E3 and Panasonic’s GX850 (also known as the GX800 or GF9). Both targeting enthusiasts stepping up from smartphones or earlier crop-sensor cameras, they promise a good balance of portability, image quality, and creative control. But deciding between these two involves more than just comparing specs - you need to understand how they truly behave in the field across multiple photographic niches.

Having tested both cameras extensively over thousands of shots and hours of operation, I want to share my deep-dive assessment. We’ll dissect the nuances that separate them, backed by hands-on experience and technical scrutiny, so you can pick the right tool to elevate your photography art. Let’s jump in.

Getting Hands-On: Size, Ergonomics, and Controls

The Fuji X-E3 is a classic rangefinder-style mirrorless, known for blending vintage charm with modern usability. Panasonic’s GX850 adopts a similar form factor but shrinks it down further for ultra-portability. Let’s start by looking at their physicalities.

At 121 x 74 x 43 mm and 337g, the Fuji X-E3 is noticeably bigger and heavier than the 107 x 65 x 33 mm, 269g GX850. Fuji’s camera has a more substantial grip area and dedicated dials that provide tactile feedback - a boon during fast shooting or when adjusting settings without looking away.

Looking from above, Fuji’s X-E3 respects classical control layouts with dedicated shutter speed, exposure compensation dials, and an aperture ring on compatible lenses, emphasizing manual control for enthusiasts.

Meanwhile, the GX850 takes a minimalist approach, with fewer physical controls and more reliance on its touchscreen interface.

I remember shooting street portraits with both - Fuji’s weight and grip felt reassuring for stability, while Panasonic’s light build made it less intrusive to carry around all day, fitting neatly in small bags or jacket pockets.

Ergonomics verdict: Fuji X-E3 is best if you prefer tactile controls and a traditional manual feel, while Panasonic GX850 is ideal if size/weight and selfie-friendly design are your primary concerns.

Sensor Technology and Image Quality: APS-C vs Four Thirds

Likely the most critical component to your results: the sensor. Here Fuji and Panasonic diverge sharply.

The X-E3 sports a 24MP APS-C X-Trans CMOS III sensor (23.6 x 15.6 mm) - larger and more resolution-heavy than the GX850’s 16MP Micro Four Thirds sensor (17.3 x 13 mm).

From experience, the X-Trans sensor’s unique color filter array reduces moiré even without an anti-aliasing filter, resulting in sharper, cleaner images with excellent detail rendition - especially noticeable when shooting landscapes or portraits. Fuji’s sensor also has a wider native ISO range (200-12,800 native ISO, expandable up to 51,200), and I found it handling low light significantly better, offering improved dynamic range and lower noise beyond ISO 3200.

The GX850, despite a smaller sensor and 16MP resolution, is not a slouch. Panasonic’s Venus Engine image processor provides solid color science and decent noise performance for Four Thirds. However, when pixel-peeping or cropping heavily, you start seeing more noise and less fine detail compared to the X-E3.

The difference is evident when printing or pixel-peeping large crops - you gain image quality and flexibility with the bigger APS-C sensor. Of course, Micro Four Thirds systems often benefit from more compact lenses, which sometimes compensates for the sensor gap depending on your shooting style.

Viewing Experience: Viewfinder and LCD Screens

Both cameras have 3” 1040k-dot LCD screens, but here the Panasonic GX850 pulls ahead in selfie-friendliness with a tilting touchscreen that flips up a full 180 degrees - perfect for vlogging or self-portraits.

Fuji’s X-E3 screen is fixed but offers touch capabilities for focus and menu navigation. The X-E3 impresses more with its quality electronic viewfinder (EVF) boasting a high 2.36-million-dot resolution, 0.62x magnification, and 100% coverage, vital for composing in bright conditions or classic viewfinder enthusiasts.

Panasonic dropped the EVF altogether in the GX850, so you rely solely on the LCD for framing. This might feel unnatural to some photographers used to eye-level composition or when shooting in strong sunlight.

In practical terms, I often found myself missing the EVF on the GX850 during daylight outdoor shooting. Fuji's EVF clarity helps nail focus and exposure more confidently.

Autofocus Systems: Speed and Accuracy

Autofocus performance can make or break a photo session, especially when shooting portraits, wildlife, or sports.

The Fuji X-E3 uses a hybrid AF system with 325 focus points combining phase and contrast detection. Fuji’s implementation delivers quick, snappy focus acquisition, especially with face and eye detection that’s quite reliable even at wide apertures. In my experience, continuous AF can track moving subjects smoothly, useful for casual sports or street shooting.

Panasonic’s GX850 relies on contrast-detection AF with 49 points and includes advanced features like Post Focus and Focus Stacking. While contrast AF is generally slower than phase detection, Panasonic enhances accuracy, and the GX850 performs well for static subjects or slower-moving scenarios.

Still, for fast wildlife or sports shooters, the X-E3's phase detection array and faster frame rate (up to 14 fps vs GX850’s 10 fps) provide a clear advantage.

Image Stabilization: What to Expect?

Neither camera offers in-body image stabilization (IBIS), which may be a deal-breaker for some. You’ll need stabilized lenses or steady hands, especially at telephoto or macro distances.

Lens Ecosystem: Fujifilm X Mount vs Micro Four Thirds

Lens compatibility profoundly influences your creative potential.

Fuji’s X mount boasts 54 prime and zoom lenses ranging from ultra-wide to super-telephoto and specialized glass optimized for its APS-C sensors. The lens quality is generally excellent - Fuji primes especially deliver gorgeous color rendition and sharpness, enhancing the X-E3’s sensor advantages.

Panasonic’s Micro Four Thirds mount is arguably the most extensive mirrorless lens ecosystem, with over 100 lenses from Panasonic, Olympus, and third-party manufacturers. Many lenses are compact, inexpensive, and versatile.

The tradeoff? MFT lenses have a 2.1x crop factor (vs. 1.5x on Fuji), so a 50mm on MFT acts like 105mm on full-frame, affecting wide-angle capabilities.

For landscape and portraits where wide apertures and fast primes matter, Fuji’s lineup is superior in optical quality at the high end. For travel and casual shooting, Panasonic’s smaller lenses and broader availability appeal.

Video Capabilities: Which Shines?

Both cameras support 4K video, but implementation varies.

• FujiFilm X-E3 shoots 4K UHD at 20p, 24p, and 25p with H.264 encoding but lacks advanced video features like 4K at 30p, headphone jacks, or in-body stabilization.

• Panasonic GX850 supports 4K UHD at 30p and 24p, with higher bitrate H.264 encoding and 4K photo modes that let you extract 8MP stills from video clips - a useful creative tool for action or wildlife photography.

Panasonic’s GX850 does not include a microphone input, which limits serious videographers, while the X-E3 offers an external mic port but no headphone jack.

For casual 4K video and social media creators who value 4K photos, the GX850 holds a slight edge. For hybrid shooters wanting more manual video options, Fuji’s mic port is a positive.

Battery Life and Storage

The Fuji X-E3 excels in battery life - rated for 350 shots versus Panasonic’s 210 shots (both using their proprietary lithium-ion packs). In my testing, Fuji’s camera comfortably lasts a day of shooting, while Panasonic may need a spare battery for extended sessions.

In terms of storage, Fuji uses full-sized SD cards, while Panasonic uses microSD. Both cameras have a single card slot.

Durability and Weather Sealing

Neither camera offers official weather sealing, dustproofing, or shock/freeze-proof ratings. They are best confined to fair-weather shooting or handled with care in rough situations.

Price and Value

At launch and still generally today, the Fuji X-E3 retails higher around $700, while the Panasonic GX850 is more budget-friendly near $550.

Given the technically superior sensor, build quality, and autofocus system on the Fuji, that price premium makes sense, but Panasonic’s camera remains a highly attractive, capable choice for entry-level buyers.

Real-World Performance Across Photography Genres

Let’s break down how these cameras perform in various popular photographic disciplines based on my experience:

Portrait Photography

Fuji’s X-E3 really shines here. Its color rendition and skin tone reproduction benefit from Fujifilm’s acclaimed film simulations, making portraits vivid and natural. The 325 point autofocus with face and eye detection locks quickly and reliably, delivering sharp focus on eyes - crucial for engaging portraits. The larger sensor also facilitates a creamier bokeh with fast primes.

Panasonic’s GX850 can deliver pleasing portraits, especially with bright lenses, but the smaller sensor yields somewhat less background separation and lower subject pop. The lack of eye detection AF is noticeable.

Landscape Photography

The X-E3’s dynamic range and higher resolution make it my recommendation for landscapes. Fuji’s camera pulls more detail from shadows and highlights and produces gritty high-frequency detail that prints beautifully.

Panasonic is respectable but shows less latitude in post-processing and brightness extremes.

Wildlife Photography

This is where Fuji's faster continuous shooting rate, phase-detection autofocus, and ergonomic controls clearly win out. The X-E3 locks and tracks moving subjects more effectively. Panasonic’s slower contrast-detection AF struggles with quick or erratic movements.

Sports Photography

Similar to wildlife, Fuji’s burst up to 14fps and hybrid AF provide a useful edge here, though neither camera rivals dedicated pro sports bodies. Panasonic’s 10fps is solid for casual action but less reliable for fast sequences.

Street Photography

I actually appreciate the Panasonic GX850 in this domain for its compactness and discreetness - lightweight and with no viewfinder, it’s less intrusive for candid shots. The tilting screen aids low-angle creativity and selfies.

Fuji’s X-E3 is bulkier but the tactile controls aid quick manual settings change that some street shooters prefer.

Macro Photography

Neither camera has macro-specific lenses bundled, but Panasonic edges slightly due to focus stacking and post focus features that simplify extended depth-of-field macro work. Fuji lacks these, so you rely on traditional focus bracketing workflows.

Night / Astrophotography

Fuji’s larger sensor allows cleaner high ISO performance, so shooting stars, cityscapes at night, or low-light environments comes with less noise and more detail retention.

Panasonic struggles more beyond ISO 800, showing chroma noise and loss of detail.

Sample Images from Both Cameras

Some side-by-side galleries and real photographs really help close the gap on theory vs practice.
